The way I have been weighing my cars in recent years is to take a couple news papers to the local recycling center. They weigh your car before and after you dump the junk and give you a check besides! For that you get an accurate printed document of your vehicle's weight.
The weighing the car with the bathroom scales is defiantly a cool method and 30 years ago I would have had to try it. But now I just don't have the energy and so many other things need my attention and that is how I related to the question. I just wanted to throw out a few alternatives. It is so fast and painless just to drive across the scales. I get weighed multiple times a day when I am driving, Just to haul one lead of corn to the ethanol plant involves weighing at least four times if everything goes right getting loaded.


I like the weighing the car at the recycle center method. Do they pay you for the old newspapers?

What does that have to do with a college, expecially one that tries to teach the latest technology (we are in AR)?

Could it be because latest technology has yet to meet the accuracy of a sundial?

Just remember, when all of the newfangled timekeeping devices fail, the guy who knows the principle behind the sundial will still be able to tell time.

Don't think it can't happen, I was watching a show about the electromagnetic pulse bomb.

Pulse bomb can't mess up an old bathroom scale though.....



hahahahahahahaha

Later, mikey

Unless I'm standing on it. Then the bomb will do some damage!

Don't laugh at the board method at the front of the thread. I too am a mech eng and did exactly the same thing. I even weighed myself ( no lightweight) and it was very close. No only that it was cheap. I think I paid about 15 bucks for the scale and the wood.

He's in Madera County, probably an hour or less from Yosemite National Park. I haven't been up that way for 5 or 6 years, it's pretty rugged country, very nice if you like the outdoors.

4 pieces of copy paper and an accurate tire pressure guage. Cheapest easiest way. (no, I haven't sniffed too much nitrous)


On a flat surface, slide a sheet of paper behind, in front of and on both sides of a tire. Measure the distance front/aft & side to side. Multiply width by length, for total square inches of tire footprint. Check tire pressure. Multiply psi x the square inches. Do the same for the remaining tires. Add thewm together. and you have your weight.

I was within 8# on a 2700# race car, and a 3100# 65 chevelle.

Slide the paper in until it stops, and keep them parallel /square.



Fire suit on, blaze away!

Any scrap yard will weigh it for you for free. If you know or can befriend any local oval track racers, they can check it by individual wheel (corner) weight and maybe they'll even help you balance it out. This will go a long way towards optimizing handling. You would be amazed at how much weight is transfered, and to where, by little changes in spring pre-load at any given corner of the car. Do this while sitting in the car or put weight equal to yours in the seat.

Scales

Hi guys,
I am a scale tech by trade and specialize in vehicle scales. The bathroom scale scenario is a joke. Bathroom scales in general are crap. Placing a board between a couple bathroom scales is a bad idea. First the scales..they never work right..second the board in between or "weighbridge" is going to have some deflection..in this case probably alot of deflection.
Deflection in a vehicle scale is a very bad thing. You can take your vehicle to a truck scale to get your weight..I would recommend a CAT scale only because I have installed a few and most CAt scales consist of 3 seperate weigh decks that will sum into a gross weight but if you position the car so that the front axle is on deck 1 and the rear axle is on deck 2 this will give you front and rear loads and gross. Keep in mind that you will be getting a weight that is rounded up or down to the nearest 20 lb increment. Also, even though truck scales are regulated by the county they are in and calibrated usually every 90 days this does not gaurantee that there is not an error in the scale. If you want to get a solid weight down to the lb. you really need to buy or find someone that can rent you racing scales or sometimes called wheel weighers. These , if calibrated properly, will get you a solid weight and should put you within a couple pounds accurately. I say calibrated properly because even the scales we purchased that were factory calibrated were off round 2-4 lbs at each wheel. When your weighing race cars this is not good. Make sure the scales and vehicle are level. We just did a new electric vehicle that is going through testing for production and this is the way to go. A weigh ticket at a truck scale will run about 8-15 dollars depending where you go.
Please no bathroom scales
